Attitudes and factors affecting acceptability of self-administered cervicovaginal sampling for human papillomavirus (HPV) genotyping as an alternative to Pap testing among multiethnic Malaysian women

Acceptability and somatic mutations in cervicovaginal self-sampling for early endometrial cancer detection in women with Lynch syndrome

New molecular approaches are being developed to detect endometrial cancer using minimally invasive sampling methods. This study aims to evaluate the acceptability of self-collected cervicovaginal samples among women with Lynch syndrome, a group at high risk for developing endometrial cancer. Participants collected cervicovaginal self-samples and answered an at-home acceptability questionnaire in a cross-sectional study. Self-samples from a subset of these women were analyzed for somatic mutations using next-generation sequencing (NGS), targeting a panel of 47 genes. A total of 61 (88.4%) out of 69 eligible women participated in the study. The overall self-sampling experience was rated good or very good (N = 55, 90.2%). Most of the women were confident about correctly sampling (N = 58, 95.1%), and most reported no or mild pain (N = 56, 91.8%). During self-sample collection, most women reported feeling calm and comfortable and experiencing safety, privacy, and normality. In a pilot study using a subset of 15 samples, five somatic variants were identified in four self-samples (4/15, 26.7%) in ACVR2A, ARID1A, APC, and KMT2D. During follow-up, three out of four women with variants detected in the self-sample underwent prophylactic hysterectomy at a median of 9.1 months, while one out of four developed endometrial cancer after 3.9 years since the collection of the sample. Self-sampling is well-accepted and well-tolerated in women with Lynch syndrome and could potentially reduce some barriers associated with gynaecological surveillance. Further research is needed to evaluate the feasibility of implementing cervicovaginal self-collection and the accuracy of molecular testing for gynaecological surveillance in women with Lynch syndrome.

Differences in intention to receive clinician-collected and self-collected samples for HPV DNA testing and its determinants between heterosexual males and females in Hong Kong, China: findings of a territory-wide household survey

BACKGROUND

Human papillomavirus (HPV) infection is prevalent among people who are sexually active. This study aimed to compare the levels of behavioral intention to receive free clinician-collected and self-collected samples for HPV DNA testing and its determinants between heterosexual males and females in Hong Kong, China.

METHODS

This is a secondary analysis of a territory-wide survey conducted in Hong Kong between May 2021 and March 2022. Participants were sexually active adult Hong Kong residents who were able to communicate in English or Chinese. Invitation letters were mailed to residential addresses that were geographically randomly selected. All sexually active adult household members were invited to complete a self-administered online survey. Multivariate logistic regression analyses were fitted.

RESULTS

Out of 45,394 invitations, 1265 surveys were collected, and 487 heterosexual males and 741 females were included in the analysis. More females than heterosexual males intended to take up free clinician-collected samples for HPV DNA testing (76.7% versus 62.2%, p < 0.001). Similar proportion of heterosexual males and females intended to receive free self-collected samples for HPV DNA testing (67.8% versus 72.6%, p = 0.20). Perceived existing treatment could control sexually transmitted infections (STI) (treatment control), more concerned about STI (concern), perceived more benefits, cue to action (suggested by significant others), and self-efficacy related to HPV testing were associated with higher intention to receive clinician-collected samples for HPV testing in both groups. Heterosexual males who perceived more severe symptoms if contracted STI (identity), longer duration of STI (timeline), more negative effects of STI on their lives (consequences), more understanding of STI (coherence), and stronger negative emotions if contracted STI (emotions) also had higher behavioral intention to take up clinician-collected samples for HPV testing. In addition, perceived more benefits, cue to action, and self-efficacy related to self-collected samples for HPV DNA testing were associated with behavioral intention to take up such testing in both groups.

CONCLUSIONS

HPV DNA testing was under-utilized in Hong Kong. Free self-collected samples for HPV testing were highly acceptable by both heterosexual males and females. Illness representation of STI and the Health Belief Model could explain intentions to take up HPV DNA testing.

Novel Strategy of Training the Accredited Social Health Activists via Application-Based Telemedicine for Cervical Cancer Screening by Human Papillomavirus Self-Sampling: The TRACK Study

PURPOSE

This pilot study is aimed to analyze a novel strategy of cervical cancer screening by training of Accredited Social Health Activist (ASHA) workers via telemedicine to counsel women for human papillomavirus (HPV) self-sampling.

MATERIALS AND METHODS

This is a pilot, community-based, prospective, single-arm study. Physicians trained the ASHA workers regarding self-sampled HPV testing via a mobile application and telephonically using videos and e-pamphlets, who in turn trained the clients in community. The HPV kits were transported via prepaid courier service.

RESULTS

Four hundred and sixty-five women of age group 30-65 years were tested by 47 teletrained ASHA workers. The mean age of ASHA worker and clients was 39.47 ± 6.45 and 37.26 ± 8.38 years, respectively. Of the ASHA workers, 91.7% were satisfied with the information provided during telecounseling, 95.7% could understand the contents of mobile app easily, and 93.6% could fill the data of clients in app easily. Of the clients, 99.6% were satisfied with counseling by ASHA workers and 98% found it easy to self-sample. The acceptability of this strategy among clients was 58.2%. The feasibility of this strategy (percentage of clients who find it easy/those who did self-sampling) was around 99%. Among those screened, 11.8% were high-risk HPV-positive and 85.5% had follow-up at the study center.

CONCLUSION

The current study highlights a novel strategy of cervical cancer screening by incorporating the role of telemedicine in training ASHA workers and their role in improving the screening by home-based delivery of HPV kits with promising results.

The levels of women's awareness, experience, acceptability and preference for Vaginal Human Papillomavirus (HPV) self-sampling in three provinces of China: a cross-sectional study

BACKGROUND

The primary screening technique for precancerous lesions and cervical cancer is human papillomavirus (HPV) testing, and HPV self-sampling has been shown to be consistent with clinician sampling in terms of the accuracy of the results and may improve cervical cancer screening rates. The aim of this study was to understand the level of awareness, experience, acceptability, and preference for vaginal HPV self-sampling among women in Jiangsu, Zhejiang, and Shanghai, China, and to analyze the possible influencing factors to determine the feasibility of implementing self-sampling.

METHODS

Overall, 1793 women were included in the data analysis. A self-administered questionnaire was utilized. In addition to descriptive analysis, univariate and multivariate analyses were used to explore the associations between sociodemographic features, history of cervical cancer screening, and the level of awareness, experience, acceptability, and preference for HPV self-samples.

RESULTS

The participants' level of awareness of and experience with HPV self-sampling were moderate. A total of 88.8% of participants rated the acceptability as "high", and self-sampling was preferred by 64.2% of them for cervical cancer screening. People aged 45 to 54 years showed a preference for both clinician sampling(OR = 1.762 (1.116-2.163)) and self-sampling (OR = 1.823 (1.233-2.697)). Those who had graduated from high school or above (OR = 2.305 (1.517-3.503), OR = 2.432 (1.570-3.768), OR = 3.258 (2.024-5.244)) preferred clinician-sampling, and those with a bachelor's degree or above (OR = 1.664 (1.042-2.657)) preferred self-sampling. Middle- and high-income individuals showed no preference for either sampling method (OR < 1).

CONCLUSIONS

HPV self-sampling is widely accepted, but awareness, experience and preferences need to be improved. These results may help to adjust public health strategies for the early inclusion of HPV self-sampling as a screening method in national initiatives to prevent cervical cancer.

Knowledge, attitudes, and practices of human papillomavirus and self-sampling among adult women: a cross-sectional study

Background

This study aimed to investigate the knowledge, attitude, and practice (KAP) of human papillomavirus (HPV) and self-sampling among adult women.

Methods

The cross-sectional, questionnaire-based study included adult women at Shanghai Pudong Hospital from October 14, 2022, to March 31, 2023. The questionnaire contained demographic information, knowledge, attitude and practice dimensions. Factors associated with KAP and self-sampling were identified by multivariate logistic regression.

Results

A total of 1843 valid questionnaires were collected. The average knowledge, attitude, and practice score was 10.09 ± 5.60, 26.76 ± 3.80, and 6.24 ± 2.20, respectively. Urban residents (estimate = 0.705, p < 0.001), suburban residents (estimate = 0.512, p < 0.001), as well as individuals with undergraduate degrees and higher (estimate = 0.535, p < 0.001), were associated with good knowledge, while individuals lacking a history of HPV infection (estimate = -0.461, p < 0.001) and married individuals (estimate = -0.185, p < 0.001) were less likely to have good knowledge. Higher knowledge scores (estimate = 0.087, p < 0.001) and individuals with undergraduate education and above (estimate = 1.570, p < 0.001) were associated with a positive attitude. Being married (estimate = 0.291, p = 0.049) was associated with good practice, whereas not engaging in sexual activity (estimate = -0.959, p < 0.001) or lacking a history of HPV infection (estimate = -0.499, p = 0.011) were associated with unfavorable practices. Minorities (OR = 2.787, p = 0.038) and individuals with multiple sexual partners (OR = 2.297 for two partners, OR = 2.767 for three or more partners, p = 0.020 and p = 0.022) were positively associated with self-sampling. However, higher knowledge (OR = 0.952, p = 0.026) and attitude scores (OR = 0.929, p = 0.015) were negatively associated with self-sampling.

Conclusion

Demographic and behavioral factors significantly influenced KAP scores and self-sampling behaviors regarding HPV. Urban residency, higher education levels, positive attitudes, and minority status correlated with favorable outcomes, while factors like marriage and lack of sexual activity were associated with less favorable practices.

Patient preference and acceptability of self-sampling for cervical screening in colposcopy clinic attenders: A cross-sectional semi-structured survey

Low vaginal self-sampling has been pioneered as an important development to improve uptake of cervical screening globally. Limited research is available in specific patient groups in the UK exploring views around self-sampling to detect high-risk human papillomavirus (hrHPV) DNA. Therefore, we explored patient views to support development of a novel point-of-care self-sampling cervical cancer screening device, by undertaking a cross-sectional semi-structured questionnaire survey to explore preferences, acceptability, barriers and facilitators around self-sampling. Patients attending a colposcopy clinic, 25-64 years old, were invited to participate after having carried out a low vaginal self-sample using a regular flocked swab. Participants self-completed an anonymous 12-point questionnaire. Quantitative data were analysed in MS Excel and Graphpad Prism, and qualitative data with Nvivo. We recruited 274 patients with a questionnaire response rate of 76%. Acceptability of self-sampling was high (95%, n = 187/197; Cronbachs-α = 0.778). Participants were asked their choice of future screening method: a) low vaginal self-sampling, b) healthcare professional collected vaginal swab, c) cervical brush sample with healthcare professional speculum examination, or d) no preference. Preferences were: a) 37% (n = 74/198), b) 19% (n = 37/198); c) 9% (n = 17/198), and d) 35% (n = 70/198), showing no single option as a strong preference. Key motivators were: Test simplicity (90%, n = 170/190), speed (81%, n = 153/190) and less pain (65%, n = 123/190). Barriers included lack of confidence taking the sample (53%, n = 10/19), resulting in preference for a healthcare professional sample (47%, n = 9/19). Whilst self-sampling showed high acceptability, lack of strong preference for screening method may reflect that respondents attending colposcopy are already engaged with screening and have differing perception of cervical cancer risk. This group appear less likely to 'switch' to self-sampling, and it may be better targeted within primary and community care, focusing on under-screened populations. Any shift in this paradigm in the UK requires comprehensive education and support for patients and providers.

Understanding of cervical cancer, acceptability of HPV self-collection, and prevalence of HPV in a semi-urban setting in Bangladesh

Human Papillomavirus (HPV) self-sampling has been implemented successfully as an alternative to traditional forms of cervical cancer screening in low-resource settings. Through Bangladesh's current national cervical cancer screening program, only about 10% of the at-risk population is reached. Thus, Bangladesh is an ideal setting to consider HPV self-sampling to improve cervical cancer prevention efforts. However, the feasibility and acceptability of HPV self-sampling has not been evaluated in Bangladesh. We aimed to understand levels of HPV and cervical cancer knowledge and to evaluate the feasibility and acceptability of HPV self-sampling for cervical cancer screening in a semi-urban Bangladeshi community. Participants were recruited from a local clinic; 164 women completed a cross-sectional questionnaire about attitudes towards screening, and cervical cancer and HPV risk factor knowledge, and provided self-collected cervical samples for high-risk HPV testing. Of the participants, 4.3% tested positive for high-risk HPV and were referred for appropriate follow-up care. Nearly all participants had heard of cervical cancer, though specific knowledge was quite low. Self-sampling for high-risk HPV testing had high rates of acceptability, high rates of convenience, and very little discomfort and embarrassment reported in this study population, making implementing HPV self-sampling as a form of cervical cancer screening in Bangladesh appear feasible.

Cervical cancer prevention: Feasibility of self-sampling and HPV testing in rural and urban areas of Bolivia: An observational study

BACKGROUND

Cervical cancer is a major health problem in Latin America. In 2019, the Italian Agency for Development Cooperation (La Paz regional site) conducted a pilot study to estimate the prevalence of high-risk human papillomavirus (HPV) and the feasibility of HPV screening in Bolivia through self-sampling and portable and transportable laboratory instruments for HPV testing in urban and rural areas.

METHODS

Women aged 20-65 years from La Paz (urban area), Toro Toro (rural area), and Acasio (rural area) were enrolled in local public health centers between Dec 1, 2019, and June 30, 2021. Self-sampling was carried out with the Viba-Brush system (Rovers, Oss, Netherlands) and samples were preserved in ThinPrep containers (Hologic Corporation, San Diego, CA, USA). The GeneXpert system (Cepheid, Sunnyvale, CA, USA) for high-risk HPV testing detects HPV E6 and E7 DNA via real-time PCR in a mobile system of easy execution requiring minimal manual intervention. The system provides results in about 1 h. The hr- HPV prevalence data, overall and partial genotyping, were analyzed considering the following age groups: 20-34, 35-44, and 45-65 years old.

FINDINGS

2168 women were enrolled: 614 (28.3%) in La Paz, 743 (34.3%) in Toro Toro, and 811 (37.4%) in Acasio. Only one sample was collected from each participant. 2043 (94.2%) of 2168 samples were adequate for HPV testing. 255 (12.5%) samples were positive for high-risk HPV. Comparing the urban area (La Paz) versus rural combined areas (Acasio+Toro Toro), using a logistic model, the HPV total rate was statistically significantly higher in the city of La Paz (15.0% vs 11.4%; OR:1.37;95% CI: 1.04-1.80). Furthermore, the HPV prevalence was declining by age, and the urban/rural odds ratio was 1.50; (95% IC 1.13-19). The overall HPV 16 positivity was 2.7% (55/2043) and for HPV 18/45 was 1.8% (37/2043) without any statistically significant differences between the three BHU enrolling centers. Only the prevalence of HPV group '39/56/66/68' was significantly higher in La Paz (p<0,001) in comparison to Acasio and Toro Toro.

INTERPRETATION

The total and age-adjusted prevalence of high-risk HPV infection in rural and urban areas in Bolivia, as measured with a validated test for screening, is similar to that observed in Europe and the USA. Our study shows that a screening protocol for HPV testing with self-sampling would be feasible in urban and rural areas in Bolivia, and that the reported high occurrence of cervical cancer in Bolivia is not related to a higher rate of high-risk HPV infections. Carrying out HPV tests locally avoids the issues associated with transportation and storage of the collected material and allows the participant to wait in the clinic for the test result, overcoming the very long response time for screening test in Bolivia.

Comparison of diagnostic accuracy and acceptability of self-sampling devices for human Papillomavirus detection: A systematic review

Objective

Cervical cancer screening coverage remains low in many countries worldwide. Self-sampling approach for cervical cancer screening has a good potential to improve the screening coverage. This study aims to compare different types of HPV self-sampling devices for cervical cancer screening to identify the most accurate and acceptable device(s).

Methods

A systematic review was performed on data extracted from all studies specific to HPV self-sampling devices by searching relevant articles in PubMed, Google Scholar, Scopus, Web of Science, ScienceDirect, Cochrane Library, and EBSCO published from 2013 to October 2023. The study was registered in PROSPERO (CRD42022375682).

Results

Overall, 70 papers met the eligibility criteria for this systematic review and were included in the analysis: 22 studies reported self-sampling devices diagnostic accuracy, 32 studies reported self-sampling devices acceptability and 16 studies reported both (accuracy and acceptability). The most popular self-sampling devices were Evalyn Brush, FLOQ Swab, Cervex-Brush, and Delphi Screener. Out of overall 38 studies analyzing self-sampling devices' diagnostic accuracy, 94.7% of studies reported that self-collected specimens provided sensitivity and specificity comparable with clinician-collected samples; acceptability of Evalyn Brush, FLOQ Swab, Delphi Screener, and Colli-Pee, varied between 84.2% and 100%.

Conclusion

The self-sampling approach has a good potential to increase cervical cancer screening coverage. Evalyn Brush, Cervex-Brush, FLOQ Swab, and Delphi Screener self-sampling devices for HPV detection were the most commonly utilized and found to be the most accurate, and patient-acceptable. HPV detection accuracy using these self-sampling devices had no significant difference compared to the sampling performed by healthcare providers.

Effectiveness of Clinic-Based Patient-Led Human Papillomavirus DNA Self-Sampling among HIV-Infected Women in Uganda

In Uganda, the uptake of cervical cancer (CC) screening services is low, at 46.7%, among HIV-infected women, and only 9% of these women adhere to annual CC screening. Some studies have evaluated the possibility of community or home-based human papillomavirus (HPV) self-collected vaginal swabs, but not clinic-based HPV self-collected vaginal swabs. Therefore, we propose a study to determine the efficacy of clinic-based versus home-based HPV DNA self-sampling among HIV-infected women attending a rural HIV clinic in Uganda. We believe that a randomized, single-blinded trial would achieve this objective, and so we have chosen it to guide the study. Including a total of 382 participants from a rural HIV clinic, randomized into a ratio of 1:1 for clinic- and home-based HPV self-sampling, would allow us to appropriately ascertain the difference in the uptake of HPV self-sampling between the two arms. The Integrated Biorepository of H3 Africa Uganda Laboratory would be used as a reference laboratory for the HPV DNA extraction, typing, and sequencing. At baseline, modified Poisson regression models would be used to measure factors associated with the prevalence of HPV and uptake in both arms at baseline. Visual inspection under acetic acid (VIA), as a gold-standard test for CC to grade for CIN, would be performed at 0 and 6 months among a random sample of 75 women with a self-collected HPV sample. The difference in uptake could be determined using the intention-to-treat analysis. The difference in the groups by each variable would be summarized as the standardized mean difference (i.e., the mean difference divided by the pooled standard deviation). The predictors of the time for which participants would continue with HPV self-sampling in both arms, recovery, and Cox proportional hazards regression would be used. At the bivariate level, the associations between each independent variable and time, with the time of continuing HPV self-sampling, would be computed. Crude hazard ratios and their 95% confidence interval would be used in the presentation of the results, with p-values < 0.05 considered significant at the bivariate level. Incremental cost-effectiveness analysis (CEA) using a Markov model would be used to determine the cost of clinic-based HPV self-sampling. We believe that screening approaches to disease stratification could provide an insight into the merits and limitations of current approaches to the diagnosis of cervical cancer, and how these could eventually be implemented into HIV clinics in Uganda and other developing African countries. It is anticipated that the findings would guide the development of step-by-step guidelines for the HPV self-sampling approach.

Exploring factors associated with preferences for human papillomavirus (HPV) self-sampling among racially- and ethnically-diverse women in Minnesota: A cross-sectional study

Pap tests are still underutilized by minority women due to limited awareness of cervical cancer screening (CCS), inadequate health care access, and cultural or religious beliefs. Human papillomavirus (HPV) self-sampling, a new CCS tool, has demonstrated potential to overcome some of these barriers. In 2021, women aged 30-65 years old were recruited across Minnesota to complete an online survey. The survey assessed five outcome measures related to HPV self-sampling: (1) awareness of test; (2) self-efficacy to conduct test; (3) location preference of test (clinic vs. home); 4) collector preference (self vs. clinician); and (5) preference of CCS strategy (HPV self-sampling vs. Pap test). Modified Poisson regressions tested associations between sociodemographic variables and outcomes. A total of 420 women completed the survey, of which 32.4% identified as Non-Hispanic white, 22.2% as Hispanic, 12.6% as Black/African-American, 28.3% as Asian, 1.9% as American Indian/Alaskan Native, and 1.4% as more than two races. Few women had heard of HPV self-sampling (6.5%), but a majority reported high self-efficacy to perform self-sampling (75.3%). Women also reported higher preferences for completing an HPV test in the clinic (52.2%) and for performing a self-collected HPV test themselves (58.7%), yet would choose a traditional Pap test over HPV self-sampling (56.0%). The low level of HPV self-sampling awareness, across all racial/ethnic groups, suggests a strong opportunity to promote widespread educational efforts around this new tool. Future HPV self-sampling research efforts should examine educational interventions targeted at healthcare providers to educate and encourage women on the importance of self-collection options.

Economic and humanistic burden of HPV-related disease in Indonesia: A qualitative analysis

The burden of human papillomavirus (HPV) and HPV-related cancers and genital warts is increasing in developing countries, including Indonesia. The objective of this study was to qualitatively explore the humanistic and economic burden of these HPV-related diseases in patients in Indonesia. In 2021, in-depth interviews and focus groups were conducted with patients (N = 18) with HPV-related diseases and healthcare professionals (HCPs; N = 10) specialised in treating these patients. Interviews explored the physical, mental, social, and economic burden of HPV-related diseases. Patients emphasised the psychological and social burden of HPV-related diseases, which negatively impacted their mental state and close relationships. Treatment for HPV-related diseases was also associated with a substantial cost, which health insurance only partially alleviated. HCPs understood the physical negative impact of HPV-related diseases, but some understated patients' social, psychological, and financial burden. This research underscores the substantial economic and humanistic burden of HPV-related diseases that could be prevented by vaccination. In addition, it highlights the need for novel interventions to reduce negative psychosocial consequences of HPV-related diseases in Indonesia. Increased HCP education of the broader humanistic impacts of HPV-related diseases may improve patient support and increase awareness for preventive strategy.

Self-Collection Cervical Screening in the Asia-Pacific Region: A Scoping Review of Implementation Evidence

PURPOSE

Although cervical cancer is a disease of inequity, it can be eliminated as a public health problem through vaccination, screening, and treatment. Human papillomavirus vaginal self-collection cervical screening is a high-performance test that can increase reach of screening. This review describes the different contexts and models of care used to pilot or implement self-collection within the Asia-Pacific, measures the extent that implementation outcome measures are reported and, where available, summarizes key implementation findings.

METHODS

A scoping review was conducted by searching five databases of the peer-reviewed literature on June 20, 2022. Two researchers assessed eligibility and extracted data independently to the model of care used and the Conceptual Framework for Implementation Outcomes. A mixed-method consolidation of findings (quantitative: count and frequencies; qualitative: content analysis) was undertaken to narratively report findings.

RESULTS

Fifty-seven articles, comprising 50 unique studies from 11 countries and two special autonomous regions, were included; 82% were conducted in trials. The implementation of self-collection was conducted in low- (2%), lower-middle- (32%), upper-middle- (32%), and high-income (35%) settings, with 10 different delivery models used; 80% delivered through practitioner-supported models with diversity in how samples were processed, and treatment was offered. Acceptability (73%) and appropriateness (64%) measures were most reported, followed by adoption (57%), feasibility (48%), and fidelity (38%). Only 7% of articles reported implementation cost or penetration measures. No articles reported sustainability measures.

CONCLUSION

The literature confirms that self-collection cervical screening has been implemented within the Asia-Pacific region, with evidence demonstrating that it is acceptable and appropriate from the user's perspective. Well-designed, high-quality implementation trials and real-world evaluations of self-collection that report the breadth of implementation outcomes can support the progression toward the elimination of cervical cancer.

The Implementation of a Primary HPV Self-Testing Cervical Screening Program in Malaysia through Program ROSE-Lessons Learnt and Moving Forward

Program ROSE (removing obstacles to cervical screening) is a primary HPV-based cervical screening program that incorporates self-sampling and digital technology, ensuring that women are linked to care. It was developed based on the principles of design thinking in the context of Malaysia. The program illustrates the importance of collaborative partnerships and addressing the multi-faceted barriers from policy changes, and infrastructure readiness to the implementation of a radically new cervical screening program in communities. The paradigm shift in cervical cancer requires a monumental and concerted effort in educating both the healthcare providers and the general public. In this short review, we highlight how Pilot Project ROSE incorporated evidence-based tools that rapidly scaled up to Program ROSE. These ideas and solutions can be adapted and adopted by other countries. Notwithstanding the impact of COVID-19, it is incumbent on countries to pave the road towards the elimination of cervical cancer with pre-existing footpaths.

Acceptability of Human Papilloma Virus Self-Sampling for Cervical Cancer Screening in a Cohort of Patients from Romania (Stage 2)

(1) Background: Low patient’s adherence to conventional cervical cancer screening methods determined the need to take into consideration alternative approaches, and vaginal HPV self-sampling is one of them. We aimed to evaluate, using an online survey, the Romanian women’s acceptability of vaginal HPV self-sampling. (2) Methods: A 13-questions online survey was distributed on three Facebook groups, and the results were summarized. (3) Results: Despite of good educational background, 10.8% (n = 60) of the respondents did not know what a Pap smear is, and 33% (n = 183) were not informed about the free national cervical cancer screening program. Multivariate analysis revealed an increased likelihood of vaginal self-sampling acceptance among respondents who did not know about Pap test (OR: 7.80; 95%CI: 1.062−57.431; p = 0.021), national cervical cancer screening program (OR: 1.96; 95%CI: 1.010−3.806; p = 0.02), HPV infection (OR: 7.35; 95%CI: 3.099−17.449; p< 0.001) or HPV test (OR: 1.67; 95%CI: 0.950−2.948; p = 0.03). Moreover, women who did not previously undergo a cervical cancer screening program were more likely to accept the new screening method (OR: 1.62; 95%CI: 0.878−3.015; p = 0.04). (4) Conclusions: Our results showed high acceptability rates of vaginal HPV self-sampling among participants.

Knowledge, attitude and practice of female university students regarding human papillomavirus and self-sampling in KwaZulu-Natal, South Africa: a cross-sectional survey

BACKGROUND

Human papillomavirus (HPV) infection remains a major cause of cervical cancer. Screening practice in South Africa has remained persistently low, with the invasiveness of pelvic examination as a major barrier to screening. This occasions the need to assess women's knowledge, attitude, and practice regarding HPV testing and self-sampling.

METHOD

This is a cross-sectional quantitative study which enrolled 386 female students between the ages of 18 and 65 years at the University of KwaZulu-Natal, South Africa. Data was collected through a self-administered structured questionnaire, from February to March 2020. Data on participants' socio-demographic characteristics, knowledge, attitudes and practices regarding HPV, HPV testing and self-sampling were obtained.

RESULTS

Out of the 386 respondents, 30.6% were unaware that HPV can be transmitted through unprotected sex, only 25.1% knew about the availability of HPV vaccines in South Africa, 16.1% knew that the vaccines are accessible for free, while 79.0% were oblivious to the asymptomatic nature of HPV infection. Furthermore, a vast majority (95.8%) had never heard about self-sampling while only 1.0% had undergone HPV testing prior to this study. Although 52.9% knew that HPV testing could prevent cervical cancer, it did not positively impact screening practice. However, 57.7% of participants were willing to undergo future screening if allowed to self-sample.

CONCLUSION

Self-sampling is a more acceptable means of sample collection compared to pelvic examination. Therefore, encouraging self-sampling and providing self-sampling kits will aid increased screening participation and address certain barriers associated with HPV testing. Awareness and educational campaigns about HPV and its causative relationship with cervical cancer will occasion better attitude towards screening participation.

Human Papillomavirus Self-Sampling for Primary Cervical Cancer Screening in Under-Screened Women in Hong Kong during the COVID-19 Pandemic

The aim of this study was to assess the effectiveness of HPV self-sampling for cervical cancer screening and the best means of service delivery, with a specific focus on under-screened women, particularly during the COVID-19 pandemic. Using three arms of service delivery (social media, school outreach and underserved outreach), we recruited under-screened women aged 30–65 years from two population groups: the general public and specific underserved communities, from whom self-sampled specimens and optional clinician-sampled cervical specimens were obtained for HPV testing. A total of 521 self-sampling kits were distributed, of which 321 were returned, giving an overall uptake rate of 61.6%. The response rate was higher in the face-to-face underserved outreach (65.5%) compared to social media (22.8%) and school outreach (18.2%). The concordance for HPV detection between self-sampled and clinician-sampled specimens was 90.2% [95% confidence interval (CI) 85.1–93.8%; Cohen’s kappa 0.59 (95% CI 0.42–0.75)]. Overall, 89.2% of women were willing to have self-sampling again. In conclusion, HPV self-sampling is an effective method for cervical cancer screening and can be considered as an option, particularly in women who are reluctant or unable to attend regular screening. Various service deliveries could be considered to increase participation in cervical cancer screening.

Exploring Factors Associated with Patients Who Prefer Clinician-Sampling to HPV Self-Sampling: A Study Conducted in a Low-Resource Setting

Human papillomavirus (HPV) self-sampling (Self-HPV) is a promising strategy to improve cervical cancer screening coverage in low-income countries. However, issues associated with women who prefer conventional HPV clinical-sampling over HPV self-sampling may affect screening participation. To address this issue, our study assessed factors associated with women's preferences related to Self-HPV. This study was embedded in a large clinical trial recruiting women aged 30-49 years in a primary HPV-based study termed "3T-Approach" (for Test-Triage-Treatment), launched in 2018 at Dschang District Hospital, West Cameroon. Participants were invited to perform a Self-HPV. After the sampling and before receiving the results, participants completed a questionnaire about cervical cancer screening and their preferences and perceptions around Self-HPV. The median age of the 2201 participants was 40.6 (IQR 35-45) years. Most (1693 (76.9%)) preferred HPV self-sampling or had no preference for either method, and 508 (23.1%) preferred clinician-sampling. Factors associated with an increased likelihood of reporting a clinician-sampling preference were tertiary educational level (29.4% CI: 25.6-33.6 vs. 14.4% CI: 12.8-16.1) and being an employee with higher grade professional or managerial occupations (5.5% CI: 3.8-7.9 vs. 2.7% CI: 2.0-3.5). The main reported reason for women preferring clinician-sampling was a lack of "self-expertise". Most women (>99%) would agree to repeat HPV self-sampling and would recommend it to their relatives. HPV self-sampling in the cultural context of central Africa was well accepted by participants, but some participants would prefer to undergo clinician sampling. Health systems should support well-educated women to increase self-confidence in using HPV self-sampling.

HPV self-sampling for cervical cancer screening: a systematic review of values and preferences

INTRODUCTION

The WHO recommends human papillomavirus (HPV) cervical self-sampling as an additional screening method and HPV DNA testing as an effective approach for the early detection of cervical cancer for women aged ≥30 years. This systematic review assesses end user's values and preferences related to HPV self-sampling.

METHODS

We searched four electronic databases (PubMed, Cumulative Index to Nursing and Allied Health Literature, Latin American and Caribbean Health Sciences Literature and Embase) using search terms for HPV and self-sampling to identify articles meeting inclusion criteria. A standardised data extraction form was used to capture study setting, population, sample size and results related to values and preferences.

RESULTS

Of 1858 records retrieved, 72 studies among 52 114 participants published between 2002 and 2018 were included in this review. Almost all studies were cross-sectional surveys. Study populations included end users who were mainly adolescent girls and adult women. Ages ranged from 14 to 80 years. Most studies (57%) were conducted in high-income countries. Women generally found HPV self-sampling highly acceptable regardless of age, income or country of residence. Lack of self-confidence with collecting a reliable sample was the most commonly cited reason for preferring clinician-collected samples. Most women preferred home-based self-sampling to self-sampling at a clinic. The cervical swab was the most common and most accepted HPV DNA sampling device.

CONCLUSIONS

HPV self-sampling is generally a highly accepted method of cervical cancer screening for end users globally. End user preferences for self-sampling device, method and setting can inform the development of new and expanded interventions to increase HPV screening.

Barriers to and Facilitators of Cervical Cancer Screening among Women in Southeast Asia: A Systematic Review

In Southeast Asia, cervical cancer is the second most common cancer in women. Low coverage for cervical cancer screening (CCS) becomes a roadblock to disease detection and treatment. Existing reviews on CCS have limited insights into the barriers and facilitators for SEA. Hence, this study aims to identify key barriers and facilitators among women living in SEA. A systematic literature review was conducted on Pubmed, Embase, PsycINFO, CINAHL, and SCOPUS. Primary qualitative and quantitative studies published in English that reported barriers and facilitators to CCS were included. The Mix Methods Appraisal Tool was used for the quality assessment of the included studies. Among the 93 included studies, pap smears (73.1%) were the most common screening modality. A majority of the studies were from Malaysia (35.5%). No studies were from Timor-Leste and the Philippines. The most common barriers were embarrassment (number of articles, n = 33), time constraints (n = 27), and poor knowledge of screening (n = 27). The most common facilitators were related to age (n = 21), receiving advice from healthcare workers (n = 17), and education status (n = 11). Findings from this review may inform health policy makers in developing effective cervical cancer screening programs in SEA countries.

Acceptability and Concordance of Self- Versus Clinician- Sampling for HPV Testing among Rural South Indian Women

Background:

Despite being largely preventable, HPV-related cervical cancers continues to be the second highest cause of cancer deaths among Indian women. HPV testing using self-sampled samples may offer an opportunity to expand cervical cancer screening in India where there is currently a shortage of providers and facilities for cervical cancer screening. The study examines acceptability and concordance of self vs. clinician collected samples for HPV-relted cervical cancer screening among rural South Indian women.

Methods:

Between May and August 2017, eight mobile screening clinics were conducted among 120 eligible women in rural villages in Mysore District, India. Women over the age of 30 underwent informed consent process and then self-sampled a sample for cervicovaginal HPV DNA testing. Next, the women underwent clinical exam where the clinician collected a cervicovaginal HPV DNA sample. Following the clinical exam, all participants answered an interviewer-administered questionnaire to assess their history of cervical cancer screening and acceptability of self- and clinician-sampling methods. To assess diagnostic accuracy, concordance of self- and clinician-sampled HPV DNA specimens was calculated in addition to five measures of acceptability (feeling of caring, privacy, embarrassment, genital discomfort, and genital pain).

Results:

Study participants had a median age 39 years, about four-in-ten (41.7%) had a secondary education or above, the vast majority (87.5%) were married and only 3.4% reported having screened for cervical cancer. For all measures of participant acceptability, self-sampling was rated significantly higher than clinician-sampling. Cohen’s kappa was 0.73 (95% CI: 0.34, 1.00), indicating substantial agreement between self- and clinician-sampling.

Conclusion:

This study demonstrates that HPV self-sampling for cervical cancer screening is feasible and acceptable in a community setting among South Indian rural women. Concordance between self-sampling and clinician-sampling was adequate for screening in community settings.

Self-sampling for high-risk human papillomavirus as a follow-up alternative after treatment of high-grade cervical intraepithelial neoplasia

Women treated for high-grade cervical-intraepithelial-neoplasia (CIN) require long-term follow-up with high-risk human-papillomavirus (HPV) testing. Self-sampling for HPV is well-accepted among these patients, but its role in follow-up for this group requires investigation. The present study examined how well HPV findings from self-sampled vaginal (VSS) and urine specimens correctly identified women from this cohort with recurrent CIN2+ compared with samples collected by clinicians. At 1st post-conization follow-up, 531 patients (99.8% participation) gave urine samples, performed VSS, underwent colposcopy with punch biopsy of visible lesions and clinician-collected cervical sampling for HPV analysis and liquid-based cytology. A total of 113 patients with positive HPV and/or abnormal cytology at 1st follow-up underwent 2nd follow-up. At 1st follow-up, all patients with recurrent CIN3 had positive HPV results by all methods. Clinician sampling and VSS revealed HPV16 positivity in 50% of recurrent cases and urine sampling revealed HPV16 positivity in 25% of recurrent cases. At 2nd follow-up, all 7 newly-detected CIN2/3 recurrences were associated with HPV positivity on VSS and clinician-samples. Only clinician-collected samples detected HPV positivity for two adenocarcinoma-in-situ recurrences, and both were HPV18 positive. A total of 77 patients had abnormal cytology at 1st follow-up, for which HPV positivity via VSS yielded highest sensitivity. The HPV findings were positive from VSS in 12 patients with high-grade squamous-intraepithelial-lesions (HSIL), and 11 patients with HSIL had positive HPV findings in clinician-collected and urine samples. All methods for assessing HPV presence yielded significant age-adjusted odds ratios for predicting abnormal lesions at 1st follow-up. For overall HPV results, Cohen's kappa revealed substantial agreement between VSS and clinician sampling, and moderate agreement between urine and clinician sampling. Clinician sampling and VSS were highly concordant for HPV16. Insofar as the pathology was squamous (not glandular), VSS appeared as sensitive as clinician sampling for HPV in predicting outcome among the present cohort. Since VSS can be performed at home, this option can maximize participation in the required long-term follow-up for these women at high-risk.

Human Papilloma Virus self-sampling performance in low- and middle-income countries

Background

Screening for HPV has led to significant reductions in cervical cancer deaths in high-income countries. However, the same results have not been achieved in low- and middle-income countries (LMICs). HPV self-sampling is a novel approach that could improve screening rates.

Methods

This study’s objective is to summarize the recent literature on HPV self-sampling in LMICs, focusing on sensitivity/specificity, and feasibility/acceptability of self-sampling compared to traditional screening methods. We conducted a PubMed search for articles published in English within the last 10 years on self-sampling in LMICs.

Results

Fifty eligible articles from 26 countries were included, 19 of which came from sub-Saharan Africa and 18 from Latin America/Caribbean. Seven studies examined sensitivity, with five reporting rates higher than 91%. Six reported on specificity, which was also very high at 86–97.8%. Six studies examined self-sampling concordance with provider-collected sampling, with concordance rates ranging from 87 to 97.5%. A total of 38 studies examined the feasibility/acceptability of HPV self-sampling. Participation rates were very high in all studies, even when self-sampling was done at participants’ homes (over 89% participation). Overall, participants reported that HPV self-sampling was easy to perform (75–97%, 18 studies), painless (60–90%, nine studies), and preferred over provider-collected sampling (57–100%, 14 studies). Eight studies reported follow-up rates for participants who completed self-sampling; however, these rates varied widely-from 13.7 to 90%. The major benefits of self-sampling include convenience of screening from home, less embarrassment, and less travel. Improved education and awareness of self-sampling, combined with support from community health workers, could reduce perceptions of self-sampling being inferior to provider-collected sampling. Improving follow-up of abnormal results and improving linkages to treatment are also essential.

Conclusion

Our literature review highlights HPV self-sampling is a well-performing test that shows promise in terms of expanding screening efforts for the prevention of cervical cancer-related deaths in LMICs.

Performance of Xpert HPV on Self-collected Vaginal Samples for Cervical Cancer Screening Among Women in South Africa

OBJECTIVES

Self-sampling may increase access to cervical cancer screening in low-resource settings. Using Xpert HPV, we compared test performance of self- and clinician-collected samples in HIV-positive and HIV-negative women in South Africa.

MATERIALS AND METHODS

Three hundred thirty HIV-positive and 375 HIV-negative women in the screening group and 202 HIV-negative and 200 HIV-positive women in the referral group, aged 30-65 years, participated in the study. All women self-collected a vaginal sample, and then, a cervical sample was collected by a clinician (both tested using Xpert HPV), followed by colposcopic examination and collection of histologic specimens.

RESULTS

There was good agreement between self- and clinician-collected samples for detection of any high-risk human papillomavirus (HPV, κ = 0.72 [95% CI = 0.669-0.771]). Prevalence of HPV and sensitivity of the test to detect cervical intraepithelial neoplasia 2+ was similar in self- and clinician-collected samples. Specificity was lower in self-collected than in clinician-collected samples in both HIV-negative (self: 77.5% [95% CI = 72.8-81.8] vs clinician: 86.9% [95% CI = 82.9-90.2]) and HIV-positive (self: 44.0% [95% CI = 38.0-50.1] vs clinician: 59.7% [95% CI = 53.6-65.6]) women. Restricting the definition of screen-positive to 3 of 5 channels on HPV Xpert improved specificity in both HIV-negative (self: 83.2% [95% CI = 78.8-87.0] vs clinician: 89.7% [95% CI = 86.1-92.7]) and HIV-positive (self: 54.2% [95% CI = 48.1-60.2] vs clinician: 67.4% [95% CI = 61.5-72.9]) women.

CONCLUSIONS

The self-collected sample had good agreement with the clinician-collected sample for the detection of HPV, and restricting the HPV types may improve the specificity in HIV-positive women.

The Acceptability and Preference of Vaginal Self-sampling for Human Papillomavirus (HPV) Testing among a Multi-ethnic Asian Female Population

Vaginal self-sampling for human papillomavirus (HPV) testing can potentially increase cervical screening coverage. This study aimed to investigate the acceptability of vaginal self-sampling for HPV testing and factors that might influence a woman's preference for this as a cervical screening method. This was a cross-sectional study that recruited 725 women from the urban and suburban areas of Selangor, Malaysia. All study participants were instructed to self-collect vaginal sample using a dry flocked swab before responding to a detailed questionnaire documenting their experience and preference for self-sampling. Most of the study participants (>80%) perceived vaginal self-sampling as easy, convenient, not embarrassing, comfortable, and were confident in performing the test. This suggests high acceptability toward vaginal self-sampling for HPV testing. Of the 725 women, 83% preferred self-sampling HPV testing over healthcare personnel sampling HPV testing and Pap test. Women with higher household income and full-time employment status were more likely to prefer self-sampling. Those who had not undergone Pap test also expressed preference for self-sampling HPV testing. Convenience and women's confidence in performing a vaginal self-sampling for HPV testing were the independent key factors that influenced the preference for self-sampling method. Vaginal self-sampling for HPV testing is highly acceptable among Malaysian women. It is the preferred choice as a primary cervical screening method and serves as an alternative to healthcare-acquired sample for Pap test. PREVENTION RELEVANCE: Organized cervical cancer screening remains unachievable in many countries. Self-sampling HPV testing is an evidence-based method that can remove barriers to cervical screening. This is particularly important for developing countries in order to achieve the WHO global strategy to accelerate cervical cancer elimination.

Acceptability and Feasibility of HPV Self-Sampling as an Alternative Primary Cervical Cancer Screening in Under-Screened Population Groups: A Cross-Sectional Study

Background: Cervical cancer is one of the most common cancers in women and about 90% of cervical cancer can be reduced by regular screening. The Pap smear has been well in place as a primary cervical screening method since 1950s; however, coverage is still not optimal. This study explored the feasibility of HPV self-sampling in two under-screened population groups in Hong Kong (HK): never screened and not regularly screened females, to estimate the uptake rate and preference rate in the future. Materials and Methods: This was a cross-sectional study to explore the acceptability and feasibility of HPV self-sampling in two age groups: aged 25–35 and aged ≥45, which were reported as the highest proportion of the under-screened population in HK between 2017 and 2018. The study invited eligible women from an HPV study cohort to perform HPV self-sampling at home by themselves. The number of specimens returned from participants was recorded and used to determine the feasibility of HPV self-sampling in the community. The participants were asked to fill in the questionnaires before and after HPV self-sampling to indicate their attitudes, acceptability, and future preference for HPV self-sampling as an acceptable alternative primary cervical cancer screening method. Results: A total of 177 subjects participated in the present study and have achieved a good overall uptake rate of 73% (129/177) who returned the self-collected cervicovaginal sample for HPV testing. Among the under-screened population, there was a higher response rate in aged ≥45 than those aged 25–35. The findings also revealed that women who were under-screened, including those who have never been screened, were more likely to prefer HPV self-sampling than those who had regular screening. This study found that the acceptability of HPV self-sampling was fairly positive among the respondents. The findings also indicated that HPV self-sampling was not only beneficial to enhance their health awareness but also to promote the cervical cancer screening uptake rate, especially among the under-screened or never screened populations. Conclusions: HPV self-sampling would be a solution to overcome the perceived barriers in clinician-based screening. The findings also indicated that it could be feasible to use as an alternative primary cervical cancer screening.

Evaluation of satisfaction with three different cervical cancer screening modalities: clinician-collected Pap test vs. HPV test by self-sampling vs. HPV test by urine sampling

OBJECTIVE

Human papillomavirus testing by self-sampling and urine sampling might be alternatives to Papanicolaou test (Pap test) for cervical cancer screening (CCS), and may increase compliance and adherence thereto. The present study aimed to explore satisfaction and preferences for cervical screening modalities among Korean women.

METHODS

In total, 732 women aged between 20 and 69 years responded to a questionnaire designed to survey the women's perceived satisfaction for the 3 CCS modalities: clinician-collected Pap test, self-collected vaginal sampling (self-sampling) and urine sampling.

RESULTS

Overall satisfaction was significantly higher with both the self-sampling and urine sampling than the clinician-collected Pap test (odds ratio [OR]=2.01; 95% confidence interval [CI]=1.48-3.00 and OR=2.47; 95% CI=1.75-3.48, respectively). Psychological distress, including embarrassment, pain, anxiety, discomfort, and stress, with self-sampling and urine sampling were significantly lower than that with the Pap test. 52% of participants reported preferences for self-sampling in the next screening round.

CONCLUSIONS

Korean women were more likely to report satisfaction with alternative modalities (self-sampling and urine sampling) for CCS in comparison to the Pap test. This suggests that self-collected modalities may help with improving CCS uptake rates by eliminating burden related with the Pap test. However, further studies for test accuracy and cost-effective analysis of the alternative modalities should be conducted in order to apply CCS.

HPV self-sampling acceptability in rural and indigenous communities in Guatemala: a cross-sectional study

INTRODUCTION

Cervical cancer disproportionately burdens low-income and middle-income countries (LMICs) such as Guatemala. Self-collection testing for human papillomavirus (HPV) has been suggested as a form of cervical cancer screening to facilitate access in LMICs. This study assessed and compared the acceptability of self-collection HPV testing in two rural, indigenous and ethnically distinct communities in Guatemala: Santiago Atitlán, Sololá and Livingston, Izabal.

METHODS

All participants, women between the ages of 18 and 60, completed a questionnaire. Eligible participants were also asked to self-collect a vaginal sample and complete a questionnaire regarding comfort and acceptability. Self-collected samples were tested for high-risk HPV using the real-time PCR Hybribio kit.

RESULTS

In the indigenous community of Santiago Atitlán, of 438 age-eligible participants, 94% completed self-collection. Of those, 81% found it comfortable and 98% were willing to use it as a form of screening. In the multiethnic (Afro-Caribbean, indigenous) community of Livingston, of 322 age-eligible participants, 53% chose to self-collect. Among those who took the test, 83% found it comfortable and 95% were willing to use it as a form of screening. In Livingston, literacy (can read and/or write vs cannot read or write) was higher in women who chose to self-collect (prevalence ratio 2.25; 95% CI 1.38 to 3.68). Ethnicity, history of screening and reproductive history were not associated with willingness to self-collect in Livingston. Women in Santiago reported less prior use of healthcare than women in Livingston. Overall, 19% (106/549) of samples tested positive for high-risk HPV.

CONCLUSION

Among women willing to self-collect in rural and indigenous communities in Guatemala, self-collection for HPV testing is highly acceptable. However, willingness to try self-collection might vary across communities and settings. Women from a community that used less healthcare were more likely to choose self-collection. Further research is necessary to determine what factors influence a woman's choice to self-collect.

Is self-sampling to test for high-risk papillomavirus an acceptable option among women who have been treated for high-grade cervical intraepithelial neoplasia?

Objective

Self-sampling to test for high risk human papilloma virus (HPV) is becoming an increasingly important component of cervical cancer screening. The aim of this observational study is to examine how women treated for high-grade cervical intraepithelial neoplasia (CIN) view HPV self-sampling.

Methods

Invited to participate in the present study were patients who had undergone treatment of high-grade CIN (grade 2 or higher) and were followed-up at 6-months at the Karolinska University Hospital, Stockholm. The participants were instructed as to how to perform HPV self-sampling. Thereafter, the participants completed a questionnaire about HPV self-sampling and other cervical cancer screening methods, as well as about self-perceived risk of cervical cancer without regular gynecologic follow-up and about specific knowledge regarding HPV, CIN and cervical cancer.

Results

Altogether 479 women enrolled in this study. The participation rate was 96.6%. Nearly 75% of the participants stated they would consider performing the HPV self-sampling prior to their next gynecologic follow-up. Confidence in HPV self-sampling was a significant independent predictor of willingness to perform HPV self-sampling. However, confidence in HPV self-sampling was significantly lower than confidence in Papanicolaou smears and in HPV testing with samples collected by health professionals. Higher specific knowledge about HPV, CIN and cervical cancer was also a significant independent predictor of willingness to perform HPV self-sampling, as was having travelled longer distance to attend gynecologic follow-up. Participants with lower income and without completed university education expressed significantly higher confidence in HPV self-sampling and lower confidence in Papanicolaou smears than the other women.

Conclusions

To the best of our knowledge, this is the first study to examine the views of women treated for high-grade CIN vis-à-vis HPV self-sampling. The latter is an acceptable option for the vast majority of this cohort of women.

The incremental role of trait emotional intelligence on perceived cervical screening barriers

Researchers have become increasingly interested in investigating the role of the psychological aspects related to the perception of cervical screening barriers. This study investigates the influence of trait EI on perceived cervical screening barriers. Furthermore, this study investigates the incremental validity of trait EI beyond the Big Five, as well as emotion regulation in the perceived barrier towards the Pap test as revealed in a sample of 206 Italian women that were undergoing cervical screening. Results have shown that trait EI is negatively related to cervical screening barriers. Furthermore, trait EI can be considered as a strong incremental predictor of a woman's perception of screening over and above the Big Five, emotion regulation, age, sexual intercourse experience and past Pap test. Detailed information on the study findings and future research directions are discussed.

Safety and acceptability of human papillomavirus testing of self-collected specimens: A methodologic study of the impact of collection devices and HPV assays on sensitivity for cervical cancer and high-grade lesions

BACKGROUND

Comparative data on different self-collection methods is limited.

OBJECTIVES

To assess the impact of hrHPV testing of two self-collection devices for detection of cervical carcinoma and high-grade lesions.

STUDY DESIGN

Three hundred ten patients collected two cervicovaginal specimens using a brush (Evalyn^®Brush) and a swab (FLOQSwabs™), and filled a questionnaire at home. Then, a physician at the clinic took a cervical specimen into PreservCyt^® buffer for hrHPV testing and cytology. All specimens were tested using Anyplex™ II HPV28, Cobas^® 4800 HPV Test and Xpert^®HPV.

RESULTS

Performance comparison included 45 cervical carcinomas and 187 patients with premalignant lesions. Compared to the physician-specimen, hrHPV testing of Evalyn^®Brush showed non-inferior sensitivity for CIN3+ (relative sensitivity of Anyplex™ 0.99; Cobas^® 0.96; Xpert^®HPV 0.97) while hrHPV testing of FLOQSwabs™ showed inferior sensitivity (relative sensitivity of Anyplex™ 0.91; Cobas^® 0.92; Xpert^®HPV 0.93). Similar results were observed for invasive carcinomas albeit that FLOQSwabs™ was statistically non-inferior to the physician-specimen. Self-collection by either Evalyn^®Brush or FLOQSwabs™ was more sensitive for CIN3+ than LSIL or worse cytology. Significant decrease in sensitivity for CIN3+ were observed for FLOQSwabs™ when specimens were preprocessed for hrHPV testing after 28 days. Both devices were well accepted, but patients considered Evalyn^®Brush easier and more comfortable than FLOQSwabs™.

CONCLUSIONS

Self-collection is comparable to current screening practice for detecting cervical carcinoma and CIN3+ but device and specimen processing effects exist. Only validated procedure including collection device, hrHPV assay and specimen preparation should be used.

Prevalence and sociodemographic correlates of cervicovaginal human papillomavirus (HPV) carriage in a cross-sectional, multiethnic, community-based female Asian population

Objectives

Cervical cancer is a largely preventable disease, and the strategic implementation of a cervical cancer prevention programme is partly dependent on the impact of human papillomavirus (HPV) infection interpreted within the context of the country’s sociodemographic attributes. The objective of this study is to determine the prevalence of cervicovaginal HPV infection among a healthy, community-based, multiethnic Malaysian population. The HPV prevalence was subsequently correlated to the individual’s sociodemographics and sexual/reproductive history. Of significance, the observed prevalence captured was in a birth cohort not included in the national school-based HPV vaccination programme.

Methods

This was a cross-sectional study where 1293 healthy women aged between 18 and 60 years were recruited via convenience sampling from five community-based clinics in Selangor, Malaysia. Cervicovaginal self-samples were obtained and DNA was extracted for HPV detection and genotyping. A comprehensive questionnaire was administered to determine the sociodemographics and behavioural patterns of participants.

Results

The median age at enrolment was 37 years old (IQR: 30–47). In total, 86/1190 (7.2%) of the samples collected were positive for HPV infection, with the highest HPV prevalence (11.9%) detected in the subgroup of 18–24 years old. The top three most prevalent HPV genotypes were HPV 16, 52 and 58. The independent risk factors associated with higher rates of HPV infection included Indian ethnicity, widowed status and women with partners who are away from home for long periods and/or has another sexual partner.

Conclusions

The overall prevalence of HPV infection in this Malaysian multiethnic population was 7.2%, with 6.5% being high-risk genotypes. The top three most common high-risk HPV types were HPV 16, 52 and 58. This information is important for the planning of primary (HPV vaccination) and secondary (screening) cervical cancer prevention programmes in Malaysia.

Candidate biomarkers in the cervical vaginal fluid for the (self-)diagnosis of cervical precancer

Purpose

Despite improvement in vaccines against human papilloma virus (HPV), the causative agent of cervical cancer, screening women for cervical precancer will remain indispensable in the coming 30–40 years. A simple test that could be performed at home or at a doctor’s practice and that informs the woman whether she is at risk would significantly help make a broader group of patients who aware that they need medical treatment. Cervical vaginal fluid (CVF) is a body fluid that is very well suited for such a test.

Methods

Narrative review of cervical (pre)cancer candidate biomarkers from cervicovaginal fluid, is based on a detailed review of the literature. We will also discuss the possibilities that these biomarkers create for the development of a self-test or point-of-care test for cervical (pre)cancer.

Results

Several DNA, DNA methylation, miRNA, and protein biomarkers were identified in the cervical vaginal fluid; however, not all of these biomarkers are suited for development of a simple diagnostic assay.

Conclusions

Proteins, especially alpha-actinin-4, are most suited for development of a simple assay for cervical (pre)cancer. Accuracy of the test could further be improved by combination of several proteins or by combination with a new type of biomarker, e.g., originating from the cervicovaginal microbiome or metabolome.
